' 6 Claims. (Cl. 257-36) for example, so that it can be folded under theM In the drawing I have illustrated my preferred form of strucunfoldingand of easy securing the condenser assembly in bent shapeor straightenedout as in use.

I refer to the appended claims for a. statement of the inventioninherent in the structure illustrated and described. In the drawing:

tion of the condenser showing how I may provide 40 a bendable jointtherein.

Fig-.4 is a section taken along line 44 of Fig. 3. Fig. 5 "isa-fragmentary side elevation of the condenser when .in its bentposition.

Fig. .6 is a fragmentary side elevation of the 45 upper left hand sidemember. I

' Fig. 7 is a fragmentary side elevation of the lower left hand sideinember, and Fig.8 is a plan view of the tubing support used atthebendable portion of my condenser.

I have shown a refrigerator cabinet I, and at, the rear thereof acondenser unit marked 2. There are pipes and lconnecting up the con-""fdensei"-with the rest of the refrigeration unit.

The pipe 3 extends to the compressor 5 from the .85 top of thecondenser, and the pipe 4 extends up from the bottom of the condenser tothe top where it passes inwardly near the pip 3 and is connected to theevaporator 6 of the unit.

The mode of shipping a refrigerator is to ship the cabinet in onepackage and ship the refrigera- 5 tion unit, fullycharged and ready tooperate in another package; The cabinet, as per present practice has anupper compartment in it, which is open to the back of therefrlgeratorpand the The problem for which my invention is a soIu- 5tion, is how to arrange the condenser of the new nected up with theother parts of the unit.

The preferred mode of accomplishing this isthe condenser are separatefrom those of the lower half.

The outside strips are thicker than the fins and preferably made ofangle iron. They too have holes in them for passage of the tubing, and IV are assembled with the tubing when the fins are added.,' I-provide inthe present embodiment two upper outside stripss and two lower outsidestrips Ill. Also, preferably, I provide fora diifer- 40 enttubing-arrangement at the point where the upper and lowervoutside stripsare joined, for a purpose which will be noted. Here I interrupt thehairpin like arrangement and instead provide 7 for two straight tubingsections I I, I I, heavier union fittings H at their ends, and anS-shaped piece of copper tubing l3, which is welded into each union. I V

The support for the ends of the straight portion of tubing section H,are two metal plates 5 14. Each plate has a'hole fitted with a grommetI! for sustaining the tube section l3, and'an elongated slot It, for a'purpose to be noted. The arrangement at the right hand side is the sameas the arrangement at .the left hand side but merely set upside .down,so that no rights and lefts are required.

on the other side, the strip l0 being reversed in direction.

I will accordingly describe the left hand arrangement since the'righthand arrangement is the same thing reversed.

The lower end of the left hand strip 9|.is formed with a slot i1,terminating in a round portion l8, into which the grommet of the tubesupporting piece is thrust. It also has a slot I9, open' to the back ofthe condenser arrangement. The upper end of the left hand lower piece IDhas a slot 20, facing upwardly and terminating in a rounded portion 2|.for reception of the grommet on the supporting piece. It has also aclosed slot 22, which is spaced from the portion 2|, butwhich is anextension in the same direction of the slot 20,

There is a bolt 23 which passes through the supporting piece 14,and'through the slots in the outside strips 9 and I0. When the twostrips are in line this bolt passes through the elongated slot I6 in'thepiece l4, and slots l1 and 22 in the pieces 9 and I0. Inthis positionshown in Fig. 3, the condenser is extended in" a single plane, and heldfast in By grasping the two sections of the condenser and bending thelower half to a right angle with the upper half, which is permitted bythe bending of the S shaped pipe, and the bending of the connector pipe4, the bolt and supporting piece and outside "strips can -be brought toa fixed right angle relation as shown in Figs .5.

In this relation the bolt being first loosened, and the condenser bentto a right angle, the closed slot 22 of the lower outside strip. Hi, canbe brought in line with the slot IS, in the upper strip 9. The bolt canthenbe moved along the slot in the supporting piece l4, until it passesI through'both the slots 22 and I9, and can then be fastened. In doingso the two strips Sand ill pivot on the grommet. When fastened the boltholds the outside strips at a right angle.

When the condenser is so bent, it can be packed in such away as to lieunder the compressor -unit, and Jshus require a packaging case verylittle larger. than if the condenser were not packed. If the condenserhad to be packed in a single extended relation, it would require apacking 'case as long 'as the condenser, and considerable in theway ofsupports for the rer'nain-.

der of the unit. I I 4 When received at the point for. assembly, the

operator will. loosen the twobolts, slip them out of engaging positionwith the sidepieces, bend. thecondenser back into straight relation,

and then slide the bolts to position to lock the side pieces in theextended relation.

The only difference as to the right hand side of the arrangement is thatthe'tube supporting.

piece is reversed in position, and the bolt slides down instead of up inmaking theflnal straight line adjustment.

Other. ways of arranging for a simple joint, lockable in two positionswill suggest themselves,

and I do not limit my invention to the par-1 ticular form shown. One.essential item is that the condenser when shipped is in fully connectedposition with the rest of the refrigeration unit,

which unit iis charged withrei'rigerant, There-- fore it is undesirableto' have any'unions or revo- I The upper strip 9 on I the one side isthe same as the lower strip to this plane by the bolt.

" said side support for the two sections ,luble joints in the tubing,since all 'jointsshould be tightly sealed.

The precise construction of the two condenser sections is not anecessary item of my invention,

the important feature being that thre are two sections connected by abendable tube section.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A condenser for refrigeration units formed of a plurality ofsections, each comprising tubular elements, a; bendable tubular elementbetween the sections, and side members for the sections, said sidemembers having connections having locking means for holding thesidemembers in extended and angular relation with each other, as desired.

2. In combination, a sectional condenser formed of tubular elements,

with the side supports at an angle with relation to each other.

3. In combination, a sectional condenser formed of tubular elements,having a bendable tubular element between sections, and side supportsfor said tubular elements for each section,

them pivoting about the said bendable tubular element, and securable inpositions with the side supports in extended relation,

and in positions with the side supports at an angle with relation toeach other, the said connections comprising slotted plates through whichthe bendable tubular element passes, bolts for said slots, a slotted endon one of the side supports'of each pair, an internal slot on the otherside support of each pair, and a slot at an angle to the slotted end ofthe first noted supports, whereby the bolts passing through the slottedplates, may pass selectively either through the internal slot andslotted end, or between the internal slot and the slot at an anglehereto.
